It's displayed in compact mode, in the taskbar, in the playing track panel, in the progress bar.
The problem indeed comes from this:
I use this custom field for the titles' tag display:
$IsNull(<Titre (Traduction)>,<Title>,<Titre (Traduction)>)
<Titre (Traduction)> = <Title (Translation)> and is a custom tag
I have some artists with track titles in foreign alphabet, like japanese or russian ones.
I keep the original ones in the "track title" field, and put translation with the classical latin alphabet in the custom tag field.
The formula above check if something appears in the custom tag field, if it does, this tag is displayed instead of the track title one.
When i replace the formula with the default tag <Title>, the problem disappears, but my translation custom tag doesn't work anymore of course.
How can i keep the same kind of formula and avoid this "The" problem ?
As you can notice it in the screenshots, i use the same formula for Artist Name and Album Name, and this "The" put at the end, only affects the song title.
